Summary

The purpose of this graduate student research study is to investigate the relationship between limited ankle dorsiflexion and the potential effects on a single limb squat task in the Patellofemoral/Knee Pain population.

Detailed description

1. Participants will undergo Covid screening prior to filling out consent form and PHI. Randomization will occur to create an experimental group and a minimal intervention group. 2. Participants will complete two self-reported questionnaires on how their diagnosis affects functional activities. 3. Dorsiflexion range of motion in a weight bearing position will be taken. 4. Hip abductor strength on tested limb will be measure on isokinetic device. 5. The Lateral Step Down test will be conducted for 6 trials on each participant, 3 with a heel wedge and 3 without, movement recorded, and graded using two motion capture devices. 6. The experimental group will receive two interventions to increase dorsiflexion range of motion. The minimal intervention group will read and infographic and complete 5 minutes of treadmill walking. 7. Each participant will then have their dorsiflexion measured again prior to completing another 3 trials of the Lateral Step Down test.

Conditions

• Patellofemoral Pain

Interventions

Type	Name	Description
OTHER	Mobilization with Movement	Participants will be lunging on a box with posterior ankle glide of 10 seconds times 5 sets. They will have 30 seconds rest between trials. Participant will have their ankle taped and then walk on a treadmill at a self-selected pace for 5 minutes.
OTHER	No mobilization with movement and education	Participants ankle will not be taped and they will walk on the treadmill for 5 minutes and receive education.
